When "Buffy the vampire slayer" became more popular, it was only a matter of time until people would try to emulate its success and copy it. Even though Buffy changed channels from The WB (now The CW) to UPN (now The CW), UPN still managed to create "Special Unit 2" - a show with which UPN jumped on the bandwagon. Similarities with Buffy are mainly on the surface, as it stops with both fighting supernatural creatures. Where Buffy has them as demons, vampires and werewolves; SU2 calls them "Links", as they're the missing links between the modern ape/monkey and the modern homo sapiens. And while werewolves do exist in SU2, vampires do not - and the mere concept is seen as ridiculous. But the series never takes it too seriously, so there are some monsters that are ridiculous - like the fatmonster, which somewhat resembles the Golgothan from Kevin Smith's "Dogma" if was made of bodyfat instead of fecal matter.

Unfortunately, the series found its end when the creators of "Bureau 13", a Pen and Paper RPG, saw similarities between the show and the game. And as UPN and the creators couldn't settle on something, the show was discontinued - and never saw a DVD release.
